WINDOW-CONTROLLING- MECHANISM.

To all w hem it may concern:

- dows.

It is the object of the invention to provide a spring actuated counterbalancing arm arranged beneath a vertically slidable window member and acting upwardly thereupon, and to associate with said arm actuating means therefor and a locking mechanism under control of said actuating means.

The invention consists in the structural features and arrangement of parts hereinafter fully described-and illustrated in the accompanying drawing, wherein: b

Figure 1 isan interior view of a motor vehicle door equipped with a sliding window member to which the present invention is applied;

Figure 2" lS an enlarged view of the combined counterbalancing and locking mechanismas seen in Figure 1, the locking mechanism being shown in locked position;

1 Figure 3 is a top view of the same;

Figure 4 is a sectional view taken upon line 44 of Figure 3 and showing certain elements of the lockingmechanism which are concealed in Figure 2;

Figure 5 is a fragmentary view similar to Figure l, but showing the unlocked position of the locking mechanism, which position results from upward actuation of the actuating member.

In these views the referencev character A designates an automobile door having its lower portion chambered as indicated at A and having its upper portion formed with a vwindow opening B having a transparent closure C, which isvertically slidable and which enters the chamber A upon being lowered. The window member C is counterbalanced by a mechanism located in said chamber A and comprising an arm D having at one end a roller E adapted to bear upon the lower edge of the window member Specification of Letters Patent.

C, while its other extremity is pivoted upon a stub shaft F and. is engaged between twobracket members G and G in which said stub shaft is mounted. Said arm is spring counterbalanced, the counterbalancing effort being exerted preferably by a plurality of springs H arranged within a slot H of said arm and anchored at their outer ends at the varlous points H transversely spaced upon the arm, while the inner ends are connected through a common anchorage member to a pin H carried by one of the bracket mem bers G, G at a point above the stub shaft F. Normally the arm D is locked against pivotal movement and consequently the window member C is normally locked against sliding movement (since the free extremity of said arm engages the lower edge of said window member). To effect the desired locking, the pivotal end of the arm D is rounded about the stub shaft F and is notched to form a toothed quadrant, as indicated at H. This bracket members G, G, and maintained normally oppositely engaged with the quadrant H by a common leaf spring J. In order to effect a clockwise swinging of the arm D so as to actuate the window member downwardly. the-upper detent I must first be disengaged from the quadrant H and disengagement of the lower detent I is a prerequisite to counter clockwise swinging of the arm D, such as effects the raising of the window member.

As a common control means for the described locking mechanism and actuating means for the arm D, there is provided a handle member K adjacent the inner face of the door A, said handle member having a hub portion K, which extends into the chamber A and through which bolts L are passed, rigidly securing said handle member to an arm M within the chamber A. The end of said arm to which the hub K is bolted is formed with, a transverse slot M, which engages an enlarged portion N of the stub shaft F, the other end of said arm being pivoted upon a pin 0 carried by the arm D at one side of the axis of said arm. Prefer ably the handle member K is substantially parallel to the axis of the arm D and consequently occupies an acute angular relation to the arm M, this relation being best indicated in Figure 2. P is a trip plate {or alternatively releasing the detents I from the quadrant I-I upon actuation of the handle member K, said plate being pivoted at P upon one of the bracket members G, G at a point intermediate the two detents, and having shoulders I at opposite sides of its pivot for engagement with pins R respectively projecting from the detents I through slots S formed in the bracket member '(1. Said trip plate is furthermore formed with a pair of prongs T, which engage at each side of the circular end portion T of the arm M, in which portion the slot M is formed Normally the trip plate I is maintained in the substantiallyhorizontal position indicated in. Figure 2, in which position the shoulders P are vertical and permit engagement of the detents I with the quadrant H. This normal position of the trip plate is maintained by a coiled spring U, which is arranged vertically in a slot U, centrally formed in the plate between the prongs T, tongues U being bent at a right angle to the trip plate to form abutments for said spring. Furthermore, said spring abuts against tongues U struck out from the bracket member G and having suflicient clearance from the prongs T topermit rocking of the trip plate P between its limiting positions, one of which is shown in full. lines in, Figure 5. v

In the operation of the described invention, the, spring U abutting jointly against the tongues U and U formed respectively I upon the trip plate P and bracket member G, holds the trip plate in its horizontal position shown in Figure 2, in which position both detents I engage the quadrant II and lock the arm D against swinging either upwardly or downwardly. To swing said arm downwardly, the handle K is actuated in a downward direction and the first result is an upward swinging of the arm M about the pivot 0, so as to shift said arm to the position indicated in Figure 5. Owing to the prongs T of the trip plate embracing the circular extremity T of the arm M, said trip plate is rocked shown in F i gure 5. as the result of said pivotal movement of the arm M, and consequently the upper shoulder I of the trip plate exerts a thrust upon the pin R of the upper detent to disengage said detent from the quadrant,as is clearly seen in Figure-5. Thereupon, the arm I) will respond, by clockwise swinging to theet'fort exerted upon the handle member K, and the window member C will be lowered. Correspondingly when an upward stress is exerted upon the handle member K, the arm M is first swung downwardly about its pivot 0 within the limits established by theslot M, thus; acting upon the lowermost prong T of the tri plate to rock the latter downwardly and shlft the lower detent S out of engagement with the quadrant, andcontinued upward. pressure upon the handle member K will swing the arm D in a counter-clockwise direction and effect ralsingwof the WlIlClOW member C. Upon release of the handle member K, the spring U will return the trip plate I, the arm M and the handle K to I.

said parts being mounted upon the brack- I ets G and G.
